The tap changer has a modular design, wherein each module in each case comprises a partial winding of the control winding, which can be connected or disconnected by semiconductor switching elements.
Description
Die Erfindung betrifft einen Stufenschalter zur Spannungsregelung mit Halbleiter-Schaltelementen.The invention relates to a tap changer for voltage regulation with semiconductor switching elements.

Aus der
Bei den aus dem Stand der Technik bekannten Lösungen übernehmen Halbleiter-Schaltelemente de facto die Funktion des mechanischen Wählerarmes bei klassischen, mechanischen Stufenschaltern. Mittels der Halbleiter-Schaltelemente können einzelne Wicklungsanzapfungen der Regelwicklungen selbst zu- oder abgeschaltet werden. Es ist auch möglich, die Regelwicklung in Teilwicklungen zu unterteilen, die separat zugeschaltet werden können.In the solutions known from the prior art, semiconductor switching elements in fact assume the function of the mechanical selector arm in classical, mechanical tap changers. By means of the semiconductor switching elements individual winding taps of the control windings can be switched on or off. It is also possible to divide the control winding into partial windings, which can be switched on separately.
Nachteilig bei diesem Stand der Technik sind der hohe Schaltungsaufwand und die notwendige spezielle Anpassung der Halbleiter-Schaltelemente. Ein weiterer Nachteil des Standes der Technik besteht darin, dass beim Ausfall einzelner Halbleiter-Schaltelemente keine Regelung oder jedenfalls keine befriedigende Regelung mehr möglich ist.A disadvantage of this prior art, the high circuit complexity and the necessary special adaptation of the semiconductor switching elements. Another disadvantage of the prior art is that in case of failure of individual semiconductor switching elements no regulation or at least no satisfactory regulation is possible.
Aufgabe der Erfindung ist es, einen Stufenschalter mit Halbleiter-Schaltelementen anzugeben, der einfach aufgebaut ist. Weiterhin soll er einen modularen, erweiterbaren Aufbau besitzen. Schließlich soll der erfindungsgemäße Stufenschalter eine hohe Regelsicherheit und -genauigkeit auch beim Ausfall einzelner Schaltelemente, quasi als Notbetrieb, ermöglichen.The object of the invention is to provide a tap changer with semiconductor switching elements, which is simple. Furthermore, he should have a modular, expandable structure. Finally, the tap changer according to the invention is intended to enable a high level of control safety and accuracy even when individual switching elements fail, virtually as an emergency operation.
Diese Aufgabe wird durch einen Stufenschalter mit den Merkmalen des ersten Patentanspruches gelöst. Die Unteransprüche betreffen besonders vorteilhafte Weiterbildungen der Erfindung.This object is achieved by a tap changer having the features of the first claim. The subclaims relate to particularly advantageous developments of the invention.
Die allgemeine erfinderische Idee besteht darin, den Stufenschalter modular aufzubauen und unterschiedliche Teilwicklungen der Regelwicklung gezielt zu- bzw. gegenzuschalten. Der erfindungsgemäße Stufenschalter umfasst zwei Schaltbaugruppen, wobei die erste Schaltbaugruppe aus einer Parallelschaltung von zwei Schaltzweigen besteht und sich in jedem Schaltzweig jeweils zwei in Reihe geschaltete Halbleiter-Schaltelemente befinden. Zwischen den beiden Schaltzweigen ist eine erste Teilwicklung geschaltet. Die zweite Schaltbaugruppe besteht aus einer Parallelschaltung von drei Schaltzweigen, wobei sich in jedem Schaltzweig wiederum jeweils zwei in Reihe geschaltete Halbleiter-Schaltelemente befinden. Zwischen erstem und zweitem sowie zwischen zweitem und drittem Schaltzweig befinden sich weitere elektrische Teilwicklungen, die – ebenso wie die erste Teilwicklung – mit der Regelwicklung magnetisch gekoppelt sind, d. h. auf dem jeweiligen Trafoschenkel aufgebracht sind. Erfindungsgemäß sind die elektrischen Teilwicklungen unterschiedlich dimensioniert. Weist in einer Schaltbaugruppe eine dortige Teilwicklung eine bestimmte Zahl von Windungen auf, besitzen die anderen beiden elektrischen Teilwicklungen Windungszahlen, die ein Mehrfaches darstellen. Es ist im Rahmen der Erfindung möglich, die Zahl der einzelnen Schaltbaugruppen, die in der Gesamtheit den erfindungsgemäßen Stufenschalter bilden, zu variieren.The general inventive idea is to build the tap changer modular and selectively connect or disconnect different partial windings of the control winding. The tap changer according to the invention comprises two switch assemblies, wherein the first switch assembly consists of a parallel connection of two switch branches and in each switching branch there are in each case two semiconductor switch elements connected in series. Between the two switching branches, a first part winding is connected. The second switching module consists of a parallel connection of three switching branches, wherein in each switching branch in turn are each two series-connected semiconductor switching elements. Between the first and second as well as between the second and third switching branch are further electrical part windings, which - are magnetically coupled to the control winding - as well as the first part of the winding, d. H. are applied to the respective transformer legs. According to the invention, the electrical partial windings are dimensioned differently. If a local winding has a specific number of windings in a switching module, the other two electrical partial windings have winding numbers that are a multiple. It is possible within the scope of the invention to vary the number of individual switching assemblies that form the tap changer according to the invention in their entirety.
Beim erfindungsgemäßen Stufenschalter sind mit nur wenigen Bauteilen zum gezielten Zu- bzw. Gegenschalten der einzelnen Teilwicklungen eine große Zahl von Spannungsstufungen erreichbar. Beim erfindungsgemäßen Stufenschalter ist weiterhin eine redundante Erzeugung einzelner Teilspannungen möglich; beim im praktischen Betrieb nie auszuschließenden Ausfall einzelner Schaltelemente kann die Regelung dennoch im Wesentlichen fortgeführt werden. In the tap changer according to the invention, a large number of voltage gradations can be achieved with only a few components for selective closing or counter-switching of the individual partial windings. In the tap changer according to the invention, furthermore, a redundant generation of individual partial voltages is possible; In the case of failure of individual switching elements, which can never be excluded in practical operation, the regulation can still essentially be continued.
Die Erfindung soll nachstehend an Hand von Zeichnungen beispielhaft noch näher erläutert werden. Es zeigen:The invention will be explained in more detail by way of example with reference to drawings. Show it:
Die zweite Schaltbaugruppe B besitzt eine Parallelschaltung von drei Zweigen
Es sind im Rahmen der Erfindung auch andere Dimensionierungen der Teilwicklungen W1 ... W3 als auch der Halbleiter-Schaltelemente S1 ... S10 möglich. Within the scope of the invention, other dimensions of the partial windings W1... W3 as well as of the semiconductor switching elements S1... S10 are also possible.
Die einzelnen Halbleiterschalter sind hier beispielhaft als antiparallel geschaltete Thyristorpaare dargestellt; es sind im Rahmen der Erfindung auch andere bekannte Halbleiter-Schalter, IGBTs etwa, möglich.The individual semiconductor switches are shown here by way of example as antiparallel-connected thyristor pairs; In the context of the invention, other known semiconductor switches, IGBTs, for example, are also possible.
